Update of /cvsroot/datatype/avi/fileformat
In directory cvs01.internal.helixcommunity.org:/tmp/cvs-serv10438

Modified Files:
      Tag: hxclient_3_6_1_atlas
	avistrm.cpp 
Log Message:
Modified by:zlin@real.com
Date: 10/30/2011
Project: RealPlayer for Android Smartphones
Synopsis:c110-the avi media file can not be stoped

Overview:When playing specific avi content,the playback can
not be stopped and the status will be buffering forever.After
investigation,I found this issue was caused by the length of
index table was shorter than the real length of the media
playback.In other words,some indexes are missing at the end
of the clip.Then it will cause method FindClosestChunk return
the maximum index.However,it still not what we need.Meanwhile,
the error code HXR_NOT_INDEXABLE will be returned and indicates
we have already reached the end of the index table.In order to
conquer this question,simply update the target chunk number
according to the parameter of FindClosestChunk.It will continue
the playback even the index table end reached.In deed,it is strange
to trust index table more than the real media content.
